To resolve this error, you can change the %RV_HOME%/lib with %RV_HOME%/lib/tibrvj.jar in the property tibco.env.STD_EXT_CP in application tra and start the BW application. if this is common error with all you BW applications running on a host, then you can change the bwengin.tra file itself so that when applications are deployed they have this property set in their tra.
